New radio in unlicensed spectrum (NR-U) is an exciting evolution of LTE-U/LAA from 4G LTE to 5G NR, which generates an opportunity to alleviate the spectrum crunch in future wireless networks by operating NR in unlicensed spectrum. Due to the openness of unlicensed spectrum, networks with heterogeneous radio access technologies (RATs) will coexist with NR-U, especially for the incumbent WiFi networks. In this paper, we first introduce a NR-U framework based on network slicing and spatial multiplexing, which can help on the management of networks with heterogeneous RATs. We then propose a synchronous RAT for the proposed NR-U network and derive a user group construction strategy to improve performance as well as provide flexibility for both cellular and WiFi users. Numerical results demonstrate the mutual benefits of the proposed RAT to both cellular and WiFi users.
